How to reset Firmware Password? iMac, Lion, 10.7.3
I forgot the Firmware Password, and want to reset it.
How can I do it?
No DVD included when I bought it.
All the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, does NOT work.
To add or remove DIMMs does NOT work.
Please, give me some helpful answer.
